Description
We study possibilities of creation and detection of oscillating gravitational
fields from high energy laser beams in an optical cavity and from the ultra-
relativistic proton bunches circulating in the beam of the Large Hadron
Collider (LHC) at CERN. These sources allow for signal frequencies much
higher and far narrower in bandwidth than what most celestial sources
produce. In addition, by modulating the beams, one can adjust the source
frequency over a very broad range, from Hz to GHz. The gravitational field of
these sources and responses of three different detectors are analyzed:
a Weber-bar type mechanical rod, a detector based on superfluid helium-4
coupled parametrically to a superconducting microwave cavity, and a
monolithic pendulum. We find that with the planned high-luminosity
upgrade of the LHC and an improved design of a recently experimentally
demonstrated monolithic pendulum, a signal to noise ratio substantially larger
than 1 should be achievable. This opens new perspectives of studying
general relativistic effects and possibly quantum-gravitational effects with
ultra-relativistic, well-controlled terrestrial sources.
